Assuming your batteries are good. Check your ground. Sometimes ground wires break off the grounding point on the chassis and the items attached to that ground stop working. Are the overhead lights and other 12 v items working?

May sound simple/silly, but is the main 12V switch on? Do the ceiling lights work?

If you have a volt meter, test the battery. Fully charged should read 12.6 to 12.7 volts for a fully charged battery in good health.

Did you remove the battery recently? If so, is there a chance you could have connected the wires backwards? If so you would have popped the reverse polarity fuse in the main panel.

Can you connect to shore power? If so, do it; you're not trying to run heavy appliances like microwave or AC, so a standard extension cord adapted to 110V AC plug will work just to see if the converter is working properly. If all the above is in good working order, and your converter is working properly, you should get 12V to the coach. The lights should work in this case. Put your volt meter back on the battery; it should be reading at least 13.2 VDC if the converter is working properly (may read 13.7 or 14.2 depending on the charge stage the converter is in).

If the lights work right now, but just not those items you listed, it could be a bad ground (it could be a bad ground anyway) or some blown fuses. Check the main fuse panel for blown fuses.

I believe those are all 12V items.
Someone else asked if the ceiling lights are working?

No lights works work, the outlets are working, can't put the sliders back in... Checked the GFI outlets and they are ok. Can't figure out what else to try?

Your slides are powered by the 12 volt system, as the furnace and fridge controls are. I'm not sure about the ceiling fan you refer to. It sounds like there's a 12 volt fuse, or fuses blown in your system, or a tripped 12 volt circuit breaker. As mentioned above, a bad or disconnected ground will cause the same symptom as blown fuses. Electrical issues can be frustrating, but can be traced down with a volt meter, test light, and some time.

It's impossible to pinpoint the problem long distance, but we can suggest places to look at. Let us know what you find out.

Put a digital voltmeter on your coach batteries, for starters. Should read mid 12's, at least 12.6 volts, if your converter is working/charging when plugged into shore power. If not, there's the place to start.

Then check main fuse below the batteries or your ground wires. Sounds like you're not getting 12 volt to the rig.

going to go check suggestions above, thank you all so very much. We called RV center nearest by and they couldn't do anything for 10 days. We can drive it, can't put sliders in. They recommended a name of a fella who is an hour away and cant come for 2 days. Very frustrating. Thanks for all the advice, much appreciated.

Thanks for updating us. It's always a relief when something simple fixes it. The worst part is finding it.
